Forty six men, dressed for battle and lead by Yuranosuke, travel clandestinely by fishing boat to the city of
Kamakura and then make their way to Moron˘'s estate. Dividing into two groups, then men wait outside the
front and rear gates and prepare for their attack. Meanwhile, Moron˘, completely ignorant of the fate that
awaits him and lax in his guard, has fallen asleep after a night of singing, dancing and carousing.

When the time is right, the two groups break in simultaneously and, using a strategy devised by Yuranosuke,
successfully breach the protective shutters that surround Moron˘'s mansion, leaving the interior vulnerably
to their attack. Although the avengers are few in number, they are courageous and determined to succeed
in their mission.

Having heard the roar of battle, lords of the neighboring mansions send samurai up to the rooftops
to find out what is happening. Yuranosuke responds immediately, detailing his league's purpose and motives,
and assuring the onlookers that every precaution against fire is being taken. The neighboring samurai are
heartened by league's loyalty to the late En'ya and wish them luck in battle.

After two hours of fierce fighting, the battle is finally over and the neighborhood becomes quiet.
Although Moron˘ escapes detection for some time, he is eventually found hiding in a wood shed by Jűtar˘.
At first, in an effort to observe the proper decorum even at the moment of revenge, Yuranosuke humbly asks
Moron˘ to offer his own head without resistance; in the end, however, Moron˘ does resist and Yuranosuke
strikes a blow. The forty six men raise their voices in cheer and, using the very same dagger their lord
plunged into his own abdomen, severe Moron˘ head from his body and offer it before En'ya's memorial tablet.

As the group burns incense in memory of their lord and prepares to commit seppuku,
Wakasanosuke approaches and suggests that it would be more prudent to first withdraw to En'ya's family temple.
Yuranosuke has only just agreed to this when Yakushiji and Bannai suddenly leap out of hiding and attack.
Although the fighting is fierce, Rikiya fells them both to loud shouts of praise from the rest of the men.
